IN Nor cal, and already own a tt Noble M400 and possibly converting to a single turbo, but I have always loved the wide bodied porsche, and figured I better take the plunge while prices seem to be pretty decent.

How can you tell from the vin number what is what?
I have my eye on a couple one 89 cabrio, and a 86 slant nose.
how often does is maintenance needed?
What is the life of the engine being driven hard?
Transmission?
Is buying an all stock car going to cost a lot of money to sort out?
never driven one, but if they are half as fun as the m400 it will be a blast!
